OVERVIEW
This instrument is a highly flexible five-button portable gas
detector that can be used for leak detection, concentration
detection, and safety monitoring of LEL (lower explosive limit) and
VOL (volume ratio) of combustible gases. The instrument has a range
for detecting combustible gases at the PPM level and can be used to
detect trace gas leaks with high sensitivity for monitoring indoor
air, it is designed to meet the requirements of the latest
standards for gas detection in hazardous areas.
The GT series is suitable for detection in confined spaces, such as
sewers, underground pipes, storage tanks, and other monitoring
requirements. It has high intensity and high brightness
audio-visual alarm and toxic gas concentration early warning
performance. The user can easily operate the device with a single
button.
FEATURE
1.Measures up to 4 gases
2.Gas leak detection,Confined space monitoring
3.Integral pump with pressure sensor for flow fail detection.
Sample path is protected by a hydrophobic
filter.
4.Surveying and purging
5.PPM, LEL and Volume Methane flammable gas ranges for leak
detection
6.Manual and automatic data logging
7.Alarm:Loud audible and high visual 'ticker' (Geiger) on ppm
range.High visibility LEDs on both sides of
instrument 85 db audible alarm All alarms user programmable via
password protected menu.
8.Integral flashlight
9.Alkaline or rechargeable battery options
10.Charging via simple power cable or docking station
11.Rugged polycarbonate case, sealed to IP54
12. 7 Application Modes
Leak Test Mode: measures methane in three different distinct ranges
(ppm/LEL/%Volume). Autoranging between all three ranges, audible,
visual, and gieger alarms, and ergonomical design allows for easy
one handed operation. Also ideal for carbon monoxide
investigations.
Confined Space Mode: measures up to 4 gases (O2, LEL, CO, H2S)
simultaneously with audible visual alarms, datalogging, and min/max
values.
Bahole Mode :for testing undrerground leaks. In this mode the GT
measures gas beginning in the LEL range and autoranges to %Volume.
Barhole probe included with instrument.
Carbon Monoxide Mode: measures CO directly in ppm. Menu items for
air free CO (O2 correction) when fitted with an O2 sensor, and
differential CO.
Purge Mode: for measuring methane from 0-100% Volume in inert
atmospheres.
Sniffer Mode: enables rapid leak detection by measuring methane
0-10000 ppm with the semi-conductor fitted at the end of the flexi
probe. Audible/visual gieger allows for easy pinpointing of leaking
pipes.
Pressure Mode :measures from 0-60" of water column via a pressure
sensor on the back of the instrument. Ideal for tightness tests on
gas systems up to 2 PSI.
